- High Heat Input Welding of Al-killed Steel for Low Temperature Service (1st Report)
抄録
An investigation was carried out to improve the toughness of weldments made by high-heat-input welding of the Al-killed steel for LPG tankers and LPG storage tanks. In the present investigation sole and mutual effects of nitrogen, aluminium and titanium on the notch toughness of the weld HAZ were determined, and it was demonstrated that, when reducing nitrogen into 40 ppm or less and adding alumi-nium in excess of 0.04 %, the detrimental effects of free nitrogen could be suppressed, resulting into a remarkable improvement of HAZ toughness. Further it was also demonstrated in the present investiga-tion that the addition of micro-titanium below 0.01 % was useful for the improvement HAZ toughness. As a result, the high Al-low N-micro Ti type steel was determined to be suitable for high-heat-input welding. The present investigation was undertaken with a view to providing evidence to indicate the superior HAZ toughness of the newly developed Al-killed steel, performing various welding tests, intended for construction of LPG tanker and storage tank.
